What kind of guitar is the piano-headed coconut tree?

A coconut tree on the piano headband is a Hawaiian guitar, also called knee steel guitar, which was first invented. Use a piano box similar to a Spanish guitar. Hawaiian guitar was named because people developed its playing skills in Hawaii in the late19th century. Players can press the guitar through a steel bar or a glass rod instead of pressing the strings on the bridge with their fingers like ordinary guitars.

Guitar notes

When playing Hawaiian guitar, the player should sit in a chair with appropriate height, put his feet on the ground, put the guitar on his knee smoothly, and exert appropriate pressure on his right forearm to make the instrument more stable on his knee and avoid any unnecessary movement of the guitar. Just like the classical guitar, having the correct playing posture is beneficial to the correct pronunciation and comfort of the guitar to a certain extent, which can make the player at the best playing angle.
